I have to say, the tights performed. What I got was "good stuff" at a "cheap stuff" price. The long johns worked nicely as a top layer, although I have to say the wind did get through them more than I hoped. But my legs never really felt cold (they rarely do).
The face was the only area I really need to protect now, although I will look for some kind of bike shorts or pants than I can wear over the long johns.
I've commuted about half a dozen times in the nicer weather of September (I just started biking last month), but this was a far different experience, even from the 50 degree days in late september.
